Well then, she can lick daddy's asshole

You haul yourself up on the edge of the pool and lean back, planting your feet right next to your buttocks. "Lick daddy's asshole while he gets hard," you tell her.

Her eyes widen, but she remembers how good your anal ministrations felt to her, so she leans into your ass and starts licking around your pucker. "Mmm, good, dirty little girl," you moan. She laps at your anus, and then tries to push through it. She keeps licking at it until she can harden her tongue and enter you. You groan when she pops inside and starts wriggling around in your passage. You had a girlfriend do this once a long time ago, and you forgot how good it is. You are hard in no time at all, and when Valeria comes up for air, you get back into the pool with her.

She says, "Daddy's asshole tastes good," and bites a finger naughtily.

You chuckle and kiss her forehead. "You're a very good girl for licking daddy's ass so eagerly. As a reward, you get to pick how I take your virginity." She gasps in excitement.
